Start with x+y=10 and x-y=4
Add the equations to eliminate y:
x+y=10
+ x-y=4
2x =14
So now solve for x:
2x=14 (Divide each side by 2 to get x by itself)
x=7
Now you have solved for x, but you still need to solve for y:
x+y=10
7+y=10 (Subtract 7 from both sides to get y by itself)
y=3
Now you have both x and y but to check it, just plug it into the original equations:
x+y=10 ----> 7+3=10 (That's correct)
x-y=4 ----> 7-3=4 (That's correct)
There's your final answer.
Answer:
B and D
Step-by-step explanation:
B because if you dont and it is a real cop you would get an even bigger fine. D because you never know.
Answer:
1/3%
Step-by-step explanation:
The answer is suppose to be 36x-48
so the closest answer is 3x-4
5/3v + 4 + 1/3v = 8
first step would be to simplify...
2v + 4 = 8 <==
